The reverse of the photo provided some autographs from the esteemed players.
Terry identified himself (most reassuring) as being third from the right on the back row, and R. Tyrrell on the far right seat . Ken Girkin is easily recognisable. I can recognise Barry Holton second from the right in the back row, and a youthful Nicol Holladay third from the left seated.
